Sal married Kitty Romano, also from Baltimore, between seasons 1 and 2. It was implied that he had a crush on Ken Cosgrove. ("The Gold Violin")

On a business trip, Don Draper witnessed Sal in a compromising situation with a male bellhop. To Sal's relief, Don did not mention or ask Sal about the incident. Instead, Don pitched the slogan "Limit Your Exposure" as both an idea for an advertisement and as advice for Sal's personal life. ("Out of Town") After the incident Don gave Sal's career a boost when he suggested that Sal should direct a commercial for Patio Cola. ("The Arrangements")
